Scope Chemosynthetic communities have changed in their taxonomic composition and spatial distribution through the Earth history, but the causes and backgrounds remain to be unclear. Topics and information in various studies will be exchanged between geology, paleontology, geochemistry, and biology.? We also hope to raise some seeds of co-works on evolutionary study on chemosynthetic ecosystem.
